Various studies are being carried out for innovation on the technology both for future super/hypersonic airplanes and for reusable space transportation systems. Functions and performances of the technologies proposed should be verified in high speed conditions safely and repeatedly on the ground before flight experiments. For this purpose, so-called high-speed sled track facility is planned to be constructed. Its subscale prototype is experimentally constructed and run tests are carried out. Useful know-how is obtained about designing, fabrication, and operation of the sled track.

Keywords: High-Speed Sled Track, Water Braking, Ground Verification
